The consequence of inattentive subjects is that the EEG data do not contain any information related to visual stimuli and the most predominant signal is a slow signal drift resulting in a massive temporal correlation. Indeed, since the data in [1]} and our new data appear to be minimally affected by temporal correlations, we are only able to replicate [2]}'s results when we intentionally contaminate our data with a bias inducing temporal correlation in EEG signals and perform per-subject classification (as opposed to the pooled settings proposed in [1]}).
